Evening all. Welcome to the latest edition of "Still trying to get this 86 E150 water ready".
Just went outside after work today to add rtv sealant to both hermostat housing gaskets to stop the leaks from where I installed them without it last week. When I first got the boat I had found that someone had removed the white plastic check valve on one side and the other was melted, and thermostats were also removed completely. The check valve relief holes in the housing were plugged and sealed with flex seal... I had just finished adding them back in with all brand new parts.
Well... I got them in with the rtv sealant and now after a few minutes of running, steam started coming from the water jacket gasket and then out of the check valve hole like a tea kettle that's whistling letting you know it's ready. I stopped the engine and took the housing back off. The white plastic check valve poppet is completely melted to the spring. It was brand new... Thermostat was open and it closed as it cooled off.
Tried putting it back together without the check valve and it started spewing super hot water from the check valve hole once started. What could be causing this to happen? Should I just put it back the way it was with no tstats or check valves?
Also worth noting is I just sourced a new old stock temp sensor for it as both of the ones it had when I got it were dry rotted/crumbing and nonfunctional.
Would running it without the tstats and check valves really be a horrible thing if I don't really care about gas mileage?
